CANTON, CT — A power company report has detailed the electricity reliability in Canton, part of a recently released Eversource Energy report that details reliability statewide.
Eversource claims electric reliability for Connecticut customers has improved over the past decade, citing grid upgrades, automation technology, and vegetation management.
The company announced recently that customers now experience an average of one power interruption every 20 months, representing a 15% improvement since 2017.
Canton experienced fewer power outages than the statewide average in 2025, but residents who lost power generally faced longer outages and restoration times, according to Eversource's annual reliability scorecard.
The utility reported serving 5,315 customers in Canton during 2025.
According to the scorecard, the average Canton customer experienced one outage every 20 months, making outages less frequent than the statewide average.
However, the average customer experienced 140 minutes without power during the year, compared with a statewide average of 81 minutes.
When outages occurred, Eversource reported that it took an average of 230 minutes to restore service in Canton.
The report also found that 336 customers experienced three or more outages during the year, while 513 customers experienced at least one outage lasting seven hours or longer.
Trees remained the leading cause of power interruptions in Canton, accounting for the vast majority of outages reported by Eversource.
Equipment failures, lightning, animals, vehicles and other causes accounted for a much smaller share of outages.
The utility's cause-trend data showed tree-related outages declined from 2023 levels but continued to represent approximately 80% of outage causes in both 2024 and 2022.
Eversource publishes annual reliability scorecards for communities across its service territory to provide information about outage frequency, outage duration and restoration performance.
The company notes that individual customers may experience outage durations that are shorter or longer than community-wide averages.
Eversource released the data as part of its annual electric reliability scorecards, which provide town-by-town information for the 149 Connecticut municipalities the company serves.
“These scorecards help our customers understand how outages impact their area while highlighting some of the critical work we do every day to strengthen our electric system and make it more resilient,” Eversource Vice President of Electric Field Operations Don Scacco said in a statement.
Scacco said the company uses outage data and cost-benefit analyses to determine where investments are needed, including smart switch installations and enhanced tree-trimming programs.
The scorecards also detail the leading causes of outages in each municipality and summarize local reliability and resiliency projects completed by the utility.
Eversource said ongoing infrastructure work includes replacing aging utility poles and electric lines with stronger equipment designed to better withstand severe weather.
